Storage and Delivery of Medical Gases 1 Questions and Answers Already Passed

Storage and Delivery of Medical Gases 1 Questions and Answers Already Passed a fire breaks out in the pediatrics unit due to a faulty electrical cord. One respiratory therapist has ensured that patients with oxygen are safe your responsibility in this situation would be to prepare to shut off the zone valves to the unit A large cylinder of oxygen is described as follows: CGA-540 0.903-14NGO-RH-Ext. what does this mean? This is an ASSS safety system for a large cylinder of oxygen. "CGA" refers to the Compressed Gas Association. 540 is the number assigned by the CGA to this connection. The number 14 indicates that there are 14 threads per inch on the connector, and "RH" means they are right-handed, or that the connecting hex nut is turned clockwise to attach. "EXT" refers to external threads. A respiratory therapist has to transport a patient via air from the island of Maui to Honolulu the patient is being manually ventilated with an oxygen flow set at 10 L/min using an E cylinder of gas. The cylinder gauge reads 2000 psi. how long will it last 56 mins A respiratory therapist notices that a flowmeter plugged into the wall outlet continues to read 1 L/min even though it is not turned on what is the most appropriate action at this time? Replace the flowmeter Adjustable reducing valve Used when you need to adjust the pressure; the most common type is used with a Bourdon-type flowmeter. Advantages of flow restrictors A. Low cost, simple, reliable B. Cannot be set wrong (gravity independent) An H cylinder of oxygen is being used to deliver oxygen to a patient in a subacute care facility where no piped in oxygen is available the cylinder gauge shows a pressure of 1000psi the patient is receiving oxygen at 5 L/min by cannula. Apx how long will the cylinder gas last at this flow rate? 10 hours Anesthetic Gas Nitrous Oxide - N2O Because cylinder color is only a guideline how do you actually determine what gas is in a tank? Read the label Calculate the duration of an E cylinder with 1500 psi running at 2 L/min Formula: Duration = psi × factor/flow Calculation: 1500 × 0.28 = 420/2 =210 minutes or 3 1/2 hours Calculate the duration of an H cylinder with 150 psi running at 2 L/min 1500 × 3.14 = 4710/2 = 2355 minutes or 39 1/4 hours Colors of gas cylinders: A. Oxygen B. Carbon Dioxide C. Nitrous oxide D. Helium E. Nitrogen F. Air A. Oxygen-Green B. CarbonDioxide-Gray C. NitrousOxide-Blue D. Helium-Brown E. Nitrogen-Black F. Air-Yellow Compare indicated flow and actual flow in a compensated Thorpe flowmeter when downstream resistance occurs? Compensated Thorpe
